PBOPELLING MEANS FOR VESSELS.

To all whom it may concern:

Be it known that l, FRANK FANNING, a citizen of the United States,residing at Woodward, in the county of Woodward and State of Oklahoma,have invented certain new and useful Improvements in Propelling Meansfor Vessels, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in propelling means, especiallyadapted for vessels, and has for its object to provide means whereby avessel can be propelled by means of steam or other aeriform fluid.

Other objects and advantages of my invention will appear in the courseof the following specification.

In the accompanying drawings: Figure 1 is a longitudinal sectional view.taken through a vessel fitted with my propelling apparatus, a portion ofthe latter being shown in full, lines. Fig. 2 is a top plan view of avessel similarly fitted. Fig. 3 is a longitudinal sectional view(enlarged) taken through portions of the propelling apparatus.

Referring to the drawings, which illustrate the preferred embodiment ofmy invention, 1 desi 'nates a vessel of conventional form. Krrangedhorizontally and longitudinally of the forward part of the vessel is anintake or supply pipe 2 which extends from its opening 3, beneath thewater line at the bow of the boat to about the center thereof where itis connected by means of a union 4 to the reduced end 5 of an ejector 6.From the reduced portion 5, the ejector is substantially increased indiameter, as at 7 for a portion of its length and at 8, 8, the sides ofthe ejector are extended at right angles or perpendicularly to form areservoir 9, which is substantially drum-shaped. vAttached to the bottomof the forward perpendicular side 8 of the reservoir 9 is a mixingchamber 10. The mixing chamber is constructed of a pair of conicalfrustums 11 and 12, respectively, similarly proportioned and inclinedtoward and connected to a horizontally-extending intermediate portion13. The mixing chamber has formed as an integral portion thereof adischarge pipe 14:, which, as shown, is of a diameter substantiallygreater than that of the intake or supply pipe 2, but less than that ofthe reservoir 9.

Serial No. 509,491.

Formed in the top of the portion 7 of the ejector is a pipe or injector15 which is inclined downward and curved and extends horizontally andcentrally through the reservoir 9. The interior of the pipe 15 is formedwith a converging bore, and hence thickened, from a point near the bendtherein toward the end to form a nozzle 16 which projects into theconical frustum 11 of the mixing chamber 10 of the ejector. The interiorthickening of the pipe 15 to form the nozzle 16 serves both to cause thesteam to be emitted at a high velocity and at the same time serves toprevent any undue cooling thereof prior to its contacting with the waterin the mixing chamber.

The horizontal intermediate portion 13 of the mixing chamber 10 isprovided at its upper side with an integral circular rib or boss 17,which is provided with a suitably screw-threaded, circular interior.Arranged centrally within the circular boss 17 is an aperture 18 incommunication with the interior of the mixing chamber and screwed intothe boss is a valve casing 19 having an inverted truncated conical valveseat 20, the bottom of which registers with the aperture 18 in themixing chamber. The side of the valve casing extends up above the top ofthe boss 17 and at its upper end is provided with an externally arrangedrib or flange 21. The internal diameter 22 of the upper part of thevalve casing, as shown, is greater than that of the upper end of thetruncated conical valve seat 20, and is also beveled at its upper end,as at 23, for a purpose hereinafter described.

A valve 24: is positioned in the valve seat and is held in place bymeans of a coil spring 26 which surrounds a stem or short rod 27. Oneend of the coil spring rests on top of the valve while the other endthereof presses against the under side of a cross piece 28 to which thestem is connected or is an integral portion thereof. The lower suitablyexteriorly threaded and adapted to engage the threaded portion thereofis an internally threaded collar 32 provided with an inturned flange 33which contacts with the lower side of the flange 21 of the valve casingto lock the valve casing and associated members together. The pipe 30,as shown, is turned to one side-and passed through the side of thevessel, where it discharges. As is apparent the valve 2t can be set orregulated for any amount of pressure in the mixing chamber and will riseto allow the escape of the steam and water through the pipe whenever thepressure is excessive and overbalances the valve.

The steam or other aeritorni fluid fed through the injector may be aconstant supply or it can be fed intermittently as desired.

hat I, claim is 1. In a propelling apparatus, an intake pipe, an ejectorhaving a reduced end connected to the intake pipe, and an enlargedportion of greater diameter than the intake pipe, a reservoircommunicating with and of larger diameter than the ejector, a mixingchamber connected at one end with said reservoir and consisting of apair of conical trust-um shaped chambers connected at their smaller endsby an intermediate cylindrical portion, an inclined steam pipe extendingdownward in a curve through the enlarged portion of the ejector, andthen horizontally through the reservoir and projecting into the mixingchamber, a relief valve for the mixing chamber, and a discharge pipeconnected with said mixing chamber, and of greater diameter than theintake pipe, and of smaller diameter than the reservoir.

2. In a propelling apparatus, an ejector,

an intake pipe for said ejector, and a discharge pipe carried by said eector, said discharge p1pe be ng substantially larger than said intakepipe.
